Application filed April 9,

This invention relates to cash registers, and 'i'nore specifically to the mechanism for resetting the totalizers to Zero.

The invention is shown applied to machines ot the type shown and described in the patents to F. L. Fuller, Nos. 1342,170 and 1,394,256, issued Oct. 9, 1917 and Oct. 18, 1921, respectively, and in a patent to B. M. Shipley, No. 1,619,796 issued March 1, 1927.

ders the operation of the device much more efficient, there is not only a great reduction in the number of parts, but the time within which the operation may take place has been lengthened.

Key/Z2 oarcl.

Machines of the type to which this invention is shown applied are provided with a. plurality of banks of amount keys which are identical. with the bank of keys shown in Fig. 1. As these keys and their cooperating; mechanism are fully described and illustrated in the above mentioned patents, only a very brief description thereof will be included herein.

he keys 20 of each bank are slidably mounted in a key frame 21 which is supported at its top and bottom by rods 2-2 mounted in the machine side frames. The keys are depressible and are held in their depressed positions by a detent E23 and a locl ing plate (not shown). They are released near the end of the operation by means of a shaft 24-, arms 25 and rods 26 in a manner well. known in the art.

There are also one or more banks of control keys which may be used for clerks, transactions, etc.

Difcrcvza rial mach am'sm.

The differential mechanism of the machine is old in. the art. There are a plurality ott differential units, one for each bank of keys and one or more differential units to provide overflow from the amount banks. One of these units sh ,wn in Fig. 1. Each of these units is driven by a pair of cams 27 and 28 fast on a main drive shaft 30 which is given a complete counter-clockwise rotation on each operation of the machine by any suit able means, such as a motor or crank.

Cooperating with the cams 27 and 28 are two antifriction rollers 31 and respectively, carried by a Y-shaped lever 33 pivotally mounted on one of the differential unit supporting members 34:. These supporting members for all of the differential units are carried by two rods 85 and 36 which in turn are supported by the machine side frames. Pivotcd to the upper end of the Y-shaped member is a link 37 which in turn is pivoted to a driving segment 38 pivotally mounted on a bushing 40 carried by the diflerential supporting members 34-. By theseconnections when the shaft is given its coin Jlete rotation tie driving segment 38 will he rocked first counter-clockwise and then clockwise to normal position. 7

Also pivoted on the bushing d0 are two plates 4-1 between which riveted totalizer actuating segments Normally there are three of these segments in machines 01". this type, as it is desired to actuate three separate lines of totalizers tl'lQl'Cnlllll. the operation of the machine it is necessary to latch the driving segment 38 to the totalizer actuating segments 4-2. In fact, this is the normal position of the parts. This is accomplished by means of a latch member which is movably mounted on an arm iii and a bell cran r lli which are in turn pivoted to extensions of the plates ll. The latch member 48 normally on gee a shaurlder 416 of the driving segment 88 so that when the segment is given its counter-clockwise movement by the means above described, it will carry the totalizer actuating segments '42 with it. It is desired, however, when the totalizer actuating segments have moved a distance corresponding to the value of the key depressed that a separation will be cliected between the driving segment and the totalizer actuating segments alnd the latter locked in their adjusted positions.

p This is accomplished by the following 1nechanism. When the totalizer actuating segments are given their counter-cloclnvise rotation, the end -47 of the bell crank lever l5 will come in contact with the inner end of whichever one of the keys has been depressed. ll 'hen this occurs the bell crank lever will be rocked clockwise (Fig. 1) and will thereby move the latch l3 out of 'ement with the shoulder 46' on the drivsegment and at the same time engage th opposite end of said lat-ch with one of a series of notches 48 formed in a plate 50 which is supported by the dillerential sug g frames 34. T his will permit the driving segment 3 to continue its movement to its full on "at while the totalizer actuating heuts will remain in their set positions. liowever, when the driving segment 38 is rel'iin'ned to its home position, the upper end th eel will. come into contact with a stud 51 carried by the plates ll, which will thereby positively return the totaliy r actuating segments to their home positions. As will be later de cribed the tota'iiser which. to be actuated is engaged with the totalizer actuating segments d2 during the time that segments are separated from the driving segment Then when the totalizer actuating segments are returned to home position the amount corresponding to the value of the key depressed will be added on the selected totalizer, as is well known in the art.

Also pivoted to the plates 41 is a beam differentially positioned by it carried by the Y-shaped member v nich at its left hand end is bifuri surround a stud 115 carried appr midway of a linkv 53. At its ui ei end this link is pivoted to a segment 5 to one of a plurality of s The segment 54 has a plurality ierein.

sci-i bed 1 owl/62ers.

The to zers used in connection with th s much he are old and well known in this art, and it thought that a brief description thereof will be all that is necessary herein. They consist of a plurality oil. totalizer pinions (3O loosely mounted on tubes 61.

The totalizer pinions are arranged in groups, with all pinions oi each denominational order located together. In order to iele t any particular totalizer on a line for on it is necessary to slide the coin- 1/6 line until the totalizcr to be operated is opposite the diifercntial actuating segments. This s iding movement of the totalizer lines is C0111 letely described and illustrated in the above mentioned patents and it not elieved to be necessary to include :uiv description thereof her in, as this mechei "1 fon s no part of this invention.

otally mounted on two lugs 77 211d 78 projecting from the hey frame 21 (Figs. 1 and are two levers SO and 81. The lever 80 at its upper end is pivoted to a. segmental piate 82 and at its opposite end has a slot cooperating with a pin 88 carried by the upper end of the lever 81. At its lower end the lever 81 has a slot which cooperates with a pin carried by the segmental plate 8 The lever 81 normally tends to rock in a coruitenelockwise direction due to the tension a spring connected to a stud carried by a iojecting portion 85 of lever, and through SLOT; and pin conne tion between tnem "the lever 80 normally receives a clocl'w movement. The clockvise n wesnent of the lever 80 is limited however by a pin 79 carried by an extension of the lug 78. Pivoted to a projection 86 of the lever 8 is a short link 87 which carries a pin 112 bearing; freely in a similar link 88, which, in tur is pivoted, to one arm of a three-armed spider Si). This spider is pivotally mounted upon the bushing 10 which supports the diil'er'. movable members. Each arm of the spider SO'is provided with a hook-shaped portion 91 having a projecting nose 92 which is normally in such a position as to in t out of the path oft movement of the long the guided by studs 89, carried by one of the plates 3 1, which studs extend into the hool; portions 91. At their ends the studs have flanges which maintain the hook portions in engagen'ient therewith.

The spider 71 which rocks the selected totalizer line into engageme it with the totalizer actuating segments is connected by a hub 9% to an arm {)5 (Figs. 3 and 5). The arm 95 is fastened to said hub by two screws 96 the heads of which project into short slots 97 in a plate 98 which forms a part of he supporting means for the tota lever plate and its cooperating; mechanism. can thus be seen that when the spider 71 is the extent of the slots 97.

Pivotcd to the plate 98 is a. lever 100 6) carrying a roller 101 which is adapted to engage with a slot 10?. cut in the total lever plate. At its upper end the lever 100 is bifurcatcd and surrounds a stud 103 carried by the lower end of a link 10%, which at its upper end is pivoted to an arm 105 fast on a shaft 106 supported by the 1112 chine aide frames. The slot 102 in the total lever plate is so formed that whenever the total lever 75') is moved out of its normal addingposition the arm 10) willv be rocked counterclockwise about its pirot, which, due to the engagement of its bifurcated end with thestud 108 will move said stud downwzu'dly into a cut-a 'ay portion 107 located at the upper end of the arm 95. It can. thus be that when the arm is rocked clockwise, due to the movement of the siider 71, to engage the selected totalizer line, the left hand end 108 of the cutaway portion 107 will engage with the stud 103, and
